3 Claims. (Cl. 220-65)' This invention relates to waste handling means more particularly for use in doctors and dentists oices and examination and operating rooms. Heretofore, it has been customary with permanent metal Waste receptacles having hinged lids, generally pedal actuated, to provide an inner metal container or pail which in turn receives a paper bag or the like for the actual reception of the waste, the metal pail being removable with the bag, or the bag with the Waste therein being removable alone, in either case it being customary to wash or otherwise cleanse the removable pail at suitable intervals in the use of the receptacle. This practice has made no provisions for an integral bag supply magazine and has required a ba gsupply source separate from the receptacle.

An important object of the present invention is the provision of a unitary package insert for the metal receptacle that provides both a bag vsupply compartment and a waste receiver compartment, this unitary insert being advantageously made of foldable cardboard or the like and being disposable after the supply of bags is exhausted, thereby eliminating both the necessity for cleansing and the requirement for a separate storage facility for the bags.

In an important aspect, the invention contemplates that the waste receiver portion of the device may be lined with metal foil for Ienhanced sanitation thus further eliminating the necessity for the inner pail, heretofore used with such receptacle.

An additional aspect of the invention is the provision of a cap frame, preferably of metal, that covers the insert when in use, said frame having a deck portion that conceals the supply of bags and an open frame portion that maintains the bag in the receiver compartment distended for use, .depending anges of the frame entering the mouth of the bag for that purpose.

The invention will be understood by reference to the following description, taken together with the accompany ing drawing, showing an illustrative form and application thereof in use, in which drawing- Figure 1 shows a device in accordance with the present invention about to be inserted into a metal receptacle, the upper end of which is shown;

Figure 2 is a vertical section through the receptacle and insert, the latter being shown fully entered into the receptacle and the cap frame thereon and being a section taken on the line 2 2 of Fig. 4;

Figure 3 is a similar vertical section rotated ninety del grees, being a section taken on line 3 3 of Fig. 4;

Figure 8 shows an illustrative bag in folded condition prior to use; and

Figure 9 is a complete assembled view and being a perspective of the arrangements shown also in Figs. 2 and 3 but with the receptacle cover shown raised.

Referring in detail to the drawing, the metal receptacle 11 is of rectangular cross-section and has a cover 12 that is hinged thereto as at 13, a pedal 14 being actuated to raise the cover through a lever 15 on fulcrum rod 15a, link 16 and lug 17 on cover 12, such receptacle being commonly in use in doctors and dentists oces and the like and generally having above the pedal mechanism a false bottom aiforded as shown in this instance byv a series of transverse bars 18, upon which is generally supported a removable pail that again receives a paper bag or the like for the reception of waste and refuse.

Turning now to the expedients of the present invention, and in accordance therewith, there is here shown, to take the place of the pail or inner metal container, a disposable insert 19 that as best seen in Figs. 1 and 6 is made to.

form two parallel side by side portions or compartments 20 and 21 with a common wall 22 between them. The larger of the two compartments 20 is desirably provided with an inner metalized surface such as aluminum foil facing 23. The compartment 21 may have a bottom ap 24 and the compartment 20 a bottom flap 24a. It is to be understood that the entire device 19 being advantageously made of cardboard is foldable to substantially flat form by first raising the bottom flaps 24 and 24a and then distorting the compartments from rectangles to parallelograms. Furthermore, the entire insert so constructed being manifestly of low cost is a light weight disposable unit.

When the insert 19 is straightened out, as shown in Figure l, to rectangular shape, and the bottom flaps 24 and 24a pushed down into place respectively, the com partment 21 provides a convenient storage compartment for a supply of disposable paper bags such as the bag 25 shown in Fig. 8, and when the entire device 19 is inserted into the metal waste receptacle 11 the larger compartment 20 rests on the false bottom cross-bars 18 andthe smaller compartment 22 extends downwardly behind the larger compartment and behind the cross bars as at 21a (Fig. 3). The insert thus accommodates itself to the present metal waste receptacles while at the same time providing a bag supply compartment larger in vertical length than the waste receiver compartment so that low cost bags having a seam weld 26 along their bottom edge may be used.

Upon entry of the insert 19 into the receptacle, a bag 25 may be withdrawn from the supply compartment 21 and placed in `open position in the waste receptacle compartment 20, with the mouth of the bag open in conveniently accessible condition. A bag so disposed is indicated by the numeral 32. To maintain the bag in open-mouth position, there is here shown, further in accordance with the present invention, the cap frame 27, preferably made of metal and which may be surfaced to correspond with the metal of the receptacle 11. The cap frame enters .the upper end of the receptacle to rest on the upper edges 28 of the insert 19 and desirably has flanges 2.9 and 29a, depending from its inner periphery, that enter the mouth of the bag to keep the latter distended and open. Other shorter anges 30 on its outer periphery are also shown -on the cap frame that enters the space between the receptacle 11 and the insert 19, as best seen in Fig. 2. The cap frame 4at its rear edge desirably has a deck portion 31 that constitutes a cover for the bag supply compartment 21 when the parts are in position as `shown in Figs. 2, 3 and 9. Figs. 2 and 3 show how the flanges `or aprons 29 and 29a hold the bag 32 open at the top and'in distended condition while it is in the compartment'Zl).

It is to be understood that the receptacle 11 referred to as metal might be constructed of wood.

So constructed and arranged, in accordance with the present invention, 'an insert 19 with a supply of bags 25 in the bag holding compartment 21 thereof may be shipped to the doctor or dentist, the compartment 20 being at this time folded into substantially at form adjacent the compartment 21 for compactness in shipment. When the doctor, for example, receives the insert, he enters the insert into the permanent receptacle 11 which is a part of his office equipment. He may then Withdraw one of the bags 25 from the bag supply compartment 21 and place it in open condition in the waste receiver compartment 20 which has now been straightened out from folded form to rectangular shape to conform to the inside of the permanent metal receptacle 11. He then places on top of the insert the cap frame 27 which Serves the purpose of providing a nish for the insert While concealing the raw edges of the bags Z5 and the edge of the bag placed in open position as at 32 in the waste receiver compartment 22, the anges or aprons 29 and 29a of the cap insert further serving to provide a iinished appearance for the top of the bag as well as maintaining the latter in open position. Upon pressing the pedal 14, the doctor raises the receptacle lid 12 and may then throw the waste or refuse material into the bag in the Waste receiver compartment 20 of the insert. After he has used up the supply of bags in the compartment 21, which may hold as many as 100 such bags, he may then remove the entire insert 19 from the metal receptacle 11 and discard it, placing another new insert 19 in the receptacle with a new supply of bags therein.

The invention having been described, such changes may be made therein as fall within the scope of the appended claims without departing therefrom.
